PoE Specification
1. The port 1 ~ 4 supports the PoE function.
2. Total-power: The maximum power which the switch can support to the PDs.
Notice: You must reserve about 20 W for the system. That is, if you connect an
external power supported 240W. The total power should be 220W only.
3. Schedule: The Switch allows user to arrange a week schedule to enable or disable the
PoE for the specific ports.
Perpetual POE
The Perpetual POE provides uninterrupted power to connected powered device (PD) even
when the power sourcing equipment (PSE) switch is booting .
